Cardiovascular diseases (CVDs) are the leading mortality cause worldwide, with a 60\% surge over the past three decades. In this work, we consider Computational Fluid Dynamics (CFD) tools for the description of complex intracardiac blood flow, with the ultimate goal of identifying and characterizing flow patterns indicative of the heart function. Specifically, in this contribution we consider models of the left ventricle (LV) as those described in Zheng et al. and Vedula et al. These configurations involve a closed region with moving walls, inducing fluid pumping through volume changes. Despite their simplified geometries, they serve as validation for numerical tools. We will assess the applicability of commercial Finite Volume (FV) solvers for this task, (e.g., Ansys Fluent or Star-CCM+). The plane-normal vorticity field at the end of the E-wave reveals a vortical ring which in turn encloses the asymmetric jet stream exiting from the Mitral Valve, which is a physiologically consistent pattern.
